Substrings in JavaScript

Question: How do I extract a substring from a string?

Answer: To extract a substring from a string, use the substring method:

string.substring(start,end)

Here

`string`	is the string from which you want to extract a substring.
`start`	is the number specifying the position of the character at which the substring begins. (The character at `start` itself will be included in the substring.)
`end`	is the number specifying the position of the character at which the substring ends. (The character at `end` will not be included in the substring.)

Note that the first character in the string corresponds to position 0, and the last character to position string.length-1.

Examples:

'Hello'.substring(0,2)  // 'He'
'Hello'.substring(0,4)  // 'Hell'
'Hello'.substring(1,3)  // 'el'
